I would still prefer that the final judge be a human - even if it means being told something I don't want to hear :-) I've been there, eh? But learn I do.
The ONLY reason Morse code, and we operators, were used beyond Morse's very first experiments in the early 1840s was because our brains were capable of decoding data at the "edges" of the network, where things were not reliable enough for direct data - i.e. machine to machine - connections. Morse survived because our brains made his system smart, while the others were not.
Our superior ability to provide error correction on the fly kept us relevant up until the mid-nineteen nineties when the network reliability - out to the edge - finally made us obsolete. The electronic network was now turtles all the way down.
However, a computer will never be able to appreciate that code can be beautiful. I remember "Roy's" soliloquy at the end of Blade Runner - commenting on the passing of life, and the loss of the wonders he had seen...
Anyway, computers make great training tools - and can provide feedback - but I believe the goal of all training should be to "Train the keyer in your brain" to know and good code as experience. We all know good code when we hear it - it "comes alive" in your brain. "Machine perfect" is not necessarily perfect - it does nothing to inspire wonder...
